Correct Answer: Option A
Explanation
Given: x - y = 11 (x + y)/5 = 9 Add the two equations: (6x + 4y)/5 = 20 6x + 4y = 100 Solve for x: x = (100 - 4y)/6 We could have solved for x by substituting the value of y from the first equation into the second equation. This would give us the equation: x = 28 Substituting this value for x into the first equation, we would get: y = 17 Therefore, the two numbers are x = 28 and y = 17.
